hi, is it possible to resize animated gifs with file_column? if i upload an animated gif file with file_column than the animation no longer exists... -- Posted via http://www.ruby-forum.com/.

This piece of code takes an uploaded image and resizes it. It''s a bit nasty at the moment as I am still messing around with it. What I can''t understand is why it works for one iteration but then fails with: zero-length blob not permitted `'' On the line: img = Magick::Image.from_blob(self.image).first I am basically doing this in the controller and it fails on the

I''m trying to read image data from an upload file field directly into an RMagick image object without having to temporally save the image file first. Assuming my file field param is assigned to @temp_file, i tried RMagicks from_blob method: img = Magick::Image::from_blob(@temp_file.read) But i get an error message saying that the blob is empty. I also tried feeding it the entire

I am trying to dynamically set the compression or quality of an image when displaying it. I have seen in the RMagick documentation how to set the quality only when writing the file to disk. How can I set the quality dynamically or set the compression? The method "image.quality=" does not exist and "image.compression_type=" is not in the documentation. I have tried

This doesn''t make any sense to me anymore. I have an Upload that belongs_to a Comment. Within my Upload model I expect to be able to access the associated comment with comment.foo. I can only seem to do this AFTER validation. I''m assuming before_create takes place between validation and updating the database, because when I try to access comment.foo within the validate

I'm have a (minor) problem and a question. Problem: The following code creates 5 clusters of dots of different colors. However, I need the second call outside the data.frame call to get the colors to change for some reason. I assume there's an error in the data.frame() call, but I don't know what. Question: Is there is a way to cause the resulting graphic to rotate on it's

Hi there, I have a file upload form on my page that is for images. In the model I have this: def file_data=(file_data) @file_data = file_data write_attribute ''extension'', file_data.original_filename.split(''.'').last.downcase write_attribute("content_type", file_data.content_type) write_attribute("current_name",

Greetings all, This is the first release of the SuperImage plugin. The idea is you upload images to the database, and then pull them out at any size you want. Combine this with caching and it will stay light and fast.

Tracked down the source of my problem... It seems that Rmagick isn''t properly cropping/resizing GIF or PNG images when uploaded via file_column. I can upload JPG files just fine. Originally I had installed ImageMagick via Debian''s apt-get and built the rmagick gem using "gem install rmagick". This wasn''t working so I uninstalled ImageMagick and tried to

I am using rmagick to convert files stored as a tiff to either pdf or jpg for display to the user. A snippet of test code from the controller follows. It works OK. ( it does need a sanitizer ) require RMagick def pdf @sdoc = Sdoc.find(params[:id]) @fname = ''/var/www/images/'' + @sdoc.fname @nf = Magick::ImageList.new(@fname)

So the short summary of my problem is, the batch file rsync creates is HUGE for a very small change. The idea is to create workstation image with partimage, update it with some software and send the image update diff over the wire to a large number of destinations over a satellite link, but the batch file updates are several orders of magnitude too large. I don't know exactly how partimage

Hello All, I''m using FileColumn to store images for a model in my app. I use filecolumn to scale uploaded images to different sizes. This much works fine. I then created a Ruby class for annotating text on the uploaded image. I tested this class from the shell and it works as expected. I then created a plugin for this class and hooked it up to the model. Here''s where I start

I have two problems. I have a comment that has_many uploads. Before saving the comment, I want to be sure that the upload(s) has passed validation, but I also need to validate in other ways. For example, I do not want to save the comment if there is no comment or upload. Or, I do not want to save the comment if the image has been uploaded previously (comparing md5s with past upload md5s
